CROSS REFERENCE TO RELATED APPLICATION

This application is a divisional and claims the benefit of U.S. patentapplication Ser. No. 15/721,168, filed Sep. 29, 2017 and entitled“METHOD AND SYSTEM FOR DISPLAY ASSEMBLY HINGING,” which is herebyincorporated by reference in its entirety.

BACKGROUND

The embodiments described herein relate generally to electronicequipment cabinets and, more particularly, to electronic gaming machines(EGM) including counterbalanced hinge assemblies for securing one ormore displays proximate the EGM.

At least some known EGMs include a display, also referred to as amonitor or a screen, within a cabinet housing at least a portion of theEGM. Additionally, other displays may also be associated with the EGMand be located proximate the EGM, but may not form an integral part ofthe EGM. For example, a lower display may be located next to the EGM andan upper display may be located above the EGM. The upper display may bepositioned high above a flooring surface on which the EGM is positionedthat maintenance personnel may have difficulty reaching the displaycomfortably without the use of a step ladder or other elevating device.For example, replacing and/or installing the display may require amaintenance technician lifting a monitor, which may weigh in excess offifty pounds, above the level of his head to position the monitor in itsmounted position. Climbing the elevating device while carrying thedisplay may comprise the work safety of the maintenance technician.

DETAILED DESCRIPTION

The following detailed description illustrates embodiments of thedisclosure by way of example and not by way of limitation. It iscontemplated that the disclosure has general application to physical andmethodical embodiments of a monitor hinging mechanism in industrial,commercial, and residential applications.

Embodiments of a monitor hinging mechanism are described herein. Themonitor hinging mechanism provides an improved motion controlling hingedevice, which effectively counterbalances the weight of a display membermounted in a monitor frame throughout an operative arc of its movement;automatically compensating for the variable torque (due to gravity)effects on the monitor frame as it swings between a horizontallyextending and a vertically standing attitude with respect to the floorsurface.

The following description refers to the accompanying drawings, in which,in the absence of a contrary representation, the same numbers indifferent drawings represent similar elements.

FIG. 1 is a front elevation view of an overhead display assembly 100 foran electronic machine 102. In the example embodiment, electronic machine102 is a plurality of electronic gaming machines (EGMs) ganged togetherin an island formation. Plurality of electronic gaming machines are thetype of electronic machine at which players play games with game playmedia, and which pay out game play media to players as a prize. Invarious embodiments, electronic machine 102 may be a single stand-aloneelectronic machine 102 or may have any number of electronic machine 102associated with each other by proximity whether in an island formationor not.

Overhead display assembly 100 includes a display monitor 104 supportedin a monitor frame 106 at least partially surrounding display monitor104. Monitor frame 106 includes a plurality of legs 108 coupled aroundan opening 109 through which a respective display monitor 104 isviewable. Overhead display assembly 100 is configurable in severaldifferent arrangements. Each display monitor 104 may be associated witha respective one of a plurality of EGMs 102 as shown in FIG. 1.

A single display monitor 104 may be associated with more than one or allof the plurality of EGMs 102 as shown in FIG. 2. In the exampleembodiment, overhead display assembly 100 extends vertically above theplurality of EGMs 102 in an operational position 111 as shown. As willbe shown below, overhead display assembly 100 is not supported byplurality of EGMs 102 or by a pedestal 112 on which plurality of EGMs102 are positioned and supported. Rather, overhead display assembly 100is supported separately from plurality of EGMs 102 and pedestal 112using a support stanchion 114 that can only be partially seen in FIG. 1.In various embodiments, support stanchion 114 is supported by a floorsurface 116 or a wall surface 118. In other embodiments, supportstanchion 114 is supported by a false floor assembly 120 (not shown inFIG. 1).

In theexample embodiment, support stanchion 114 includes a first anchor end302, a second coupling end 304, and a stanchion body 306 extendingtherebetween. First anchor end 302 is configured to couple to asupporting structure, such as floor surface 116. Second coupling end 304is configured to couple to a counter-balanced hinging mechanism 308. Inother embodiments, support stanchion 114 is coupled to and supported byone or more braces 310 coupled to wall surface 118, in which casesupport stanchion 114 may not extend to floor surface 116.Counter-balanced hinging mechanism 308 permits monitor frame 106 anddisplay monitor 104 to be positioned in operational position 111, amaintenance position 311, or any of a plurality of intermediatepositions between operational position 111 and maintenance position 311along an angle 312. In the example embodiment, angle 312 is greater than30° such as, but not limited to approximately 90°. In some embodiments,operational position 111 may be other than vertical, which wouldtypically make angle 312 an acute angle, or an angle less than 90°.Additionally, monitor frame 106 and display monitor 104 may bepositioned such that angle 312 is obtuse, or greater than 90°. As willbe discussed in greater detail below counter-balanced hinging mechanism308 is configured to balance the force applied to monitor frame 106 anddisplay monitor 104 by counter-balanced hinging mechanism 308 and amoment of monitor frame 106 and display monitor 104 at any of theplurality of intermediate positions between operational position 111 andmaintenance position 311. Such counter-balancing of forces and momentpermits monitor frame 106 and display monitor 104 to be manuallytranslated between operational position 111 and maintenance position 311and maintain the intermediate position when the manual urging is ceased.
